The proxies is the reason why you get spam in your Google search result, spam in your Play store (by means of fake good reviews), basically spam in anything user generated.

It directly affects Google and you, I don’t see why they should not do this.

Spam in Google search results is due to Google happily taking money from the spammers in exchange for promoting their spam, or that the spam sites benefit Google indirectly by embedding Google Ads/Analytics.

I don't see any spam in Kagi, so clearly there is a way to detect and filter it out. Google is simply not doing so because it would cut into their profits.

The reason you don't see spam in Kagi is because nobody is targeting Kagi specifically.

They can probably get away with a lot of stupid rules that would backfire if anybody tried to cater to them specifically.

"SEO spammers being more advanced than multi-billion-dollar search conglomerate" is a myth. Spam sites have an obvious objective: display ads, shill affiliate links or sell products. All these have to be visible, since an ad or product you can't see/buy is worthless. It is trivial to train a classifier to detect these.

But let's play devil's advocate and say you are right and spammers are successfully outsmarting Google - well, Kagi does use Google results via SerpAPI by their own admission, meaning they too should have those spam results. Yet they somehow manage to filter them out with a fraction of the resources available to Google itself with no negative impact on search quality.

They are not the reason. They may be one mechanism used for this.
